Specification of Letters Patent.

Application filed November 4, 1910. Serial No. 590,736.

To all whom it may concern: 7

Be it known that Enwann'F. WOOD, a citizen of theUnited States of America, residing at lVashington city, District of Columbia, has invented a newand useful Door- Hanger, of which the following is a specification.

This invention belongs to the class of hangers, being particularly a hanger adapt-v ed for freight car doors, which permits the door to be used in the most eflicient manner.

By the hereinafter described construction of hanger, the door is enabled, when being closed or opened to freely slide, and which hanger comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure l is a view of a portion of a side of a car disclosing the improved hanger construction as applied, as an illustrative showing of the application of the hanger.

Figure 2 is a sectional View through the upper part of the side of the car, showing the upper rail in plan View, and showing a part of the upper hanger.

Figure 3 is a view in elevation of the hanger, showing the hanger rail in section.

Figure 4 is an enlarged cross sectional view on line4-4 of Figure 3, showing the hanger rail, and illustrating the hanger connected to an operating crank rod of the door.

Figure 5 is a sectional view of the hanger at one end of the door of the car opposite Y the end having the crank rod.

Figure 6 is a sectional view on line 6-6 of Figure 5.

Figure 7 is a detail view in perspective of the part 16. p

In the figures, in which similar characters of reference designate similar parts, at is a door for the car body 0. It is hung on the hangers b and b which run in the track t. The hanger b is provided with a-stirrup s which is composed of the arms 1 emanating from and integral with the cap 2. The depending ends of the arms 1 meet and blend into an enlarged portion 3 of the hanger, there being integral with this portion 3 a depending stud 4 provided witha head 5.

This hanger is secured to the door by means,

of the plate 6 and thecover plate 7 with the aid of suitable bolts 8. The hanger is thus capable of a swiveling motion in its supports and sustains the weight of the door on the head 5. y

The hanger b is substantially the same as b, with the exception that instead of the stud 4, it has a larger but much shorter stud 9 which penetrates the eye of the crank rod 10 and is secured therein by a washer 11 and cotter-pin .12.

The caps 2 of the hangers are formed into globular shaped pockets of slightly larger radii than the balls 13. With this method ofmounting the balls, their surfaces are at all times tangent to the surfaces of "the pockets and they are thus permitted to slip therein and to slide along the track t.

The track If is composed of two semi-circular rails 14 and 15. sustained by the aid of Patented May 16, 1916.

the J bolts 17, and the screws 18, which pass through the spacing blocks 16 and into the 15 are secured in such a position as to provide a cylindrical bearing surface for the balls 13. For a portion of their height, the spacing blocks conform to the cross-sectional outline of the innermost rail 14 and thus offset the tendency of the track to be drawn in towards the car body. A metal cover 19 (of L section), running the entire length'of the track, covers the rail flanges and the spacing blocks. This cover is held by the J bolts 17, as they support the track, and provides what is known as a watershed.

The bottom sides of the rails 14 and 15 are separated a short distance to permit the passage'of the depending hanger arms 1.

The track t, for the greater part of its length, runs, parallel to the car body, but, at a point about in the middle of the door opening, it is directed in towards the car,

terminating at a point just suflicient to allow the offset hanger b to hold the door in flush with the car body.

The spacing blocks for the deflected portion of the track do not curve around the circular portion of the rail 14 but rest only rod 10. One of the straps 22 is just above the collar 20', to support the weight of theend 25 which cooperates with the guide track 9.

The track 9 is composed of an outer guard rail 26 and a backing plate 27. It is mounted on the blocks 28 which are held in position by the bolts 29 and screws 30. The guard rail 26 follows the same outline as the hanger track If, being deflected in toward the car body at the end. The backing plate 27 runs the entire length of the track 9 and between the car body and the 'blocks 28. For a portion of its length it bends over the blocks and, in conjunction with the guard rail' 26, provides a guideway for the lower mechanism of the door. At the point where the guide rail begins to defiect, the capping portion of the backing plate gradually diminishes and finally disappears, leaving only the thickness of the plate at the closing end of the door.

The blocks 28 at this end are, therefore, not provided with the portion for supporting the cap.

The object of this backing plate, besides providing a guideway and an operating slot for the crank rod, is to prevent any single block from being driven into the woodwork of the car-body by any excessive external shock to the outer guard rail.

A plate 34 is provided at the bottom front end of the door, to act as a keeper for the door when closed and its free end is designed to operate in the guide track 9.

To operate the door, a hasp 21 is used to impart a cranking motion to the rod 10, which causes the rear end of the door to be extracted from the opening. When the rod 10 has reached the limit of its movement the door can then be opened by sliding it along the track t, the guide-track g acting to guide the bottom of the door to its opening position.

In closing, the reverse of the operations recited above is performed, the inwardly disposed portions of-the track If, and the guide track 9 serving to direct the front end of the door into the opening.

The invention having been set forth, what is claimed as new and useful is 1. A track having a guide slot with adjacent rounded upper corner edges, hangers having globular heads arranged in the track and provided with spherical bearings,

each of said bearings being of one diameter, and spherical roller members, each of said roller members being of less diameter than each of the spherical bearings, the bearings being of such larger diameters than the roller members, as to permit the roller members to first roll in said bearing and roll on said corner edges and then. subsequently to overcoming the inertia, slip in said bearings, .and roll continuously on the adjacent rounded upper corner edges.

2. In a hanger for car doors, a ball, a

hanger having a semi-spherical cup having opposite side arms, a tubular track designed to permit a continuously rolling movement of the balll on the track, said cup of the tion of a. tubular track rail having connections with the side of the car body, and provided with a longitudinal guide slot, a hanger having a globular head and being arranged in the track and provided with a spherical bearing, a spherical device of less diameter than the spherical bearing, said spherical device being of such less diameter than the spherical bearing as to permit the device to first roll in said bearing and roll in the tubular track rail, and then subsequently to overcoming the inertia, slip in the spherical bearing, and roll continuously in the track rail. v

4. In a hanger for car doors and the like, a hanger, a ball therein, said hanger having a cup of larger radius than the ball, a hollow track permitting a continuously rolling. movement of the ball, said cup of the hanger blending into supporting means for the door, whereby the hanger will begin its movement with an alternate rolling and slipping of the ball, which in its movement gradually diminishes to a continuous slipping in said cup.

In witness whereof, the applicants signature is hereunto affixed in the presence of two witnesses.
